Title: A priori C^2 estimate for nonlinear equations I: Hessian equation

Abstract: Motivated by isometric embedding theorem, presribed curvature measure problem as well as constant rank theorem, we will discuss the global C^2 estimate for Hessian equation with general right hand side. We will focus on the main difficulty of this problem. If time permitted, we will also discuss its connections with asymptotically Pleatau problem, L_p Christoffel-Minkowski problem and self-shrinker of curvature flow.
